When I was in the Army on Tanks in 1977-78, I had a 45 and Grease Gun for Weapons. I recall the Cleaning Rod had a Slot in it and was Threaded for a Barrel Brush. The one's we had at Ft. Carson, were all Steel Parkerrized. I was hoping someone here might have a few of them, The Brass ones. I would like to buy one. I saw one on EBAY but it was sold, besided I don't buy on EBAY anyway. please rsvp. Paul in Hobe Sound, Fla.
